Question 1

How do silver points cause a problem?

Answer 1

Seltzer et al – silver wires removed from failed endodontic cases showed corrosion products of silver sulfate products which are cytotoxic.

Leakage from around the round wire within not such a round canal causes washout of the cement and fluid contact with the silver wire. Oxidation of the wire leads to the corrosive byproducts.
